Copper Alloy C96800 vs CC383H
Copper Alloy · grade comparison
Copper Alloy C96800 and CC383H are both copper alloy grades. C96800 is the stronger of the two: yield strength 655 MPa (95 ksi) against 290 MPa (42.1 ksi) for CC383H, about 126% more; tensile strength follows at 790 MPa (115 ksi) vs 480 MPa (69.6 ksi). In exchange, CC383H is the more ductile: elongation 22% versus 6% for C96800, and C96800 is harder (285 HB vs 140 HB). CC383H is stiffer (150 GPa vs 140 GPa) and CC383H runs hotter in service (300°C vs 260°C continuous). On the shop floor, C96800 machines more easily (good vs poor) and CC383H welds better (very good vs poor).
C96800Choose it when strength drives the design, or when the part is machined in volume.
CC383HChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C96800 vs CC383H: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

C96800 vs CC383H — frequently asked
Is C96800 stronger than CC383H?
Yes. C96800 has a typical yield strength of 655 MPa (95 ksi) against 290 MPa (42.1 ksi) for CC383H — about 126% more. Tensile strength is 790 MPa (115 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, C96800 or CC383H?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, C96800 or CC383H?
C96800. Its machinability rates good (55/100) against poor (32/100) for CC383H; for welding the order is CC383H first (very good, 80/100) then C96800 (poor, 30/100).
